API

chmod(path, mode, callback)

Changes the permissions of the file or directory at the specifiedpath.

• path (string): The path to the file or directory.
• mode (string ornumber): The new permissions for the file or directory. This can be a numeric mode (e.g. 666), or a string mode (e.g. 'rwxr-xr-x').
• callback (function): A callback function to call when the operation completes. The callback should take one argument, an error object, which will be null if the operation completes successfully.

importchmodfrom'chmod-cli';chmod('./test.txt','666',(err)=>{if(err)throw err;console.log('File permissions have been changed.');});

File Permissions Explanation

In the numeric notation of file permissions, each digit represents a file permission group (owner permission, user group permission, other user permission). In this notation, the numeric value for each permission is:

• Read permission:4
• Write permission:2
• Execute permission:1

Therefore,777 means:

• Owner permission:Read (4),Write (2),Execute (1) =4+2+1 = 7
• User group permission:Read (4),Write (2),Execute (1) =4+2+1 = 7
• Other user permission:Read (4),Write (2),Execute (1) =4+2+1 = 7

In total, this makes777, which means that the file's owner, members of the same user group, and all other users can read, write, and execute that file. This permission configuration is very open and should be used with caution.
